SVRGlobal is one of the best and recognised ConcentricButterfly valve manufacturer in USA. We provide high quality and cost-effective. We have an engineering-based team, due to which we can comprehend our clients’ technological needs. Concentric Butterfly valves. The concentric butterfly valve is a general-purpose butterfly valve. This valve is a flow control device that regulates the flow of the medium in the system using a rotating disc. The disc remains in the passage, but due to its thinness, it provides little/ less resistance to the flow. The stem in this type of butterfly valve travels along the middle line of the disc in the centre of the pipe bore, and the seat is the inside diameter of the valve's body. This no offset valve configuration is also known as a resilient-seated valve because the seal's reliability is dependenton the flexibility of the seat rubber when the flow is closed. The disc first interacts with the seat at about 85° for a 90° rotation in this type of valve. Concentric butterfly valves are commonly used in low-pressure applications.
Different types of connections of Concentric Butterfly valve:
· Wafer ends.
· Lug ends.
· Both flanged ends.
· Butt-welded ends.
Use of Concentric Butterfly valve:
Asconcentric butterfly valves use soft sealing material, they can only be used inbasic (water and wastewater treatment plant), special liquid (chemicals,abrasive liquids, etc.), and gases with pressures up to 200 psi and temperatures up to 400 degrees Fahrenheit.
· Water treatment.
· Water Distribution.
· Water Transmission.
· Aeration System.
· Fire Protection are some other places this valve can be used.
Advantages of Concentric Butterfly valve:
· The channel is designed as a full-diameter structure, ensuring the flow area of the valve, and lowering flow resistance when fluidpasses through the valve.
· The disc uses a dish-shaped streamline design, which not only ensures that the stress intensity at the centre of the disc is high, but alsot hat the valve has a high flow coefficient and a low fluid resistance coefficient.
